WEB looking for advice on pizza website

my brother in law is thinking about going into business with someone he works with. the guy he works with has a patent on a special type of pizza, basically each bite is like a mini pizza with crust, i don't know the details

anyways, he's thinking about getting a website setup. one of his requirements would be to have an online ordering system

i have no idea where to start with this or who to contact (i'm an it guy, but not a web developer)
